Special Hazards of Combustion Products: Irritating vapors are generated in fires. Behavior in Fire: May polymerize. Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. (USCG, 1999)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Remove all ignition sources. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.

6.3 Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Fireproof. See Chemical Dangers. Cooled. Keep in the dark. Well closed. Store only if stabilized.Before entering confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Methyl acrylate must be stored to avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) since violent reactions occur. Store in tightly closed containers in a cool, well ventilated area away from heat and moisture. At temperatures above 20°C a violent reation could take place. Methyl acrylate should always be used with an inhibitor. Check that the correct concentration of inhibitor is used; if it is not, a violent reaction could occur. Sources of ignition, such as smoking and open flames, are prohibited where methyl acrylate is handled, used, or stored. Metal containers involving the transfer of 5 gallons or more of methyl acrylate should be grounded and bonded. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of methyl acrylate. Wherever methyl acrylate is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Easily polymerizes on standing. The polymerization process can be speeded up by heat, light, and peroxides.

10.3 Possibility of hazardous reactions

Flammable liquidThe vapour is heavier than air and may travel along the ground; distant ignition possible. Vapours are uninhibited and may polymerize, causing blockage of vents.METHYL ACRYLATE ignites readily when exposed to heat, flame or sparks. Offers a dangerous fire and explosion hazard. Reacts vigorously with strong oxidizing materials. Forms peroxides when exposed to air that may initiate spontaneous exothermic polymerization. Peroxide formation usually proceeds slowly. Added inhibitor retards polymerization. If the inhibitor is consumed during long storage, explosive polymerization may occur [MCA Case History No. 2033]. Also subject to strongly exothermic polymerization if heated for prolonged periods or contaminated.

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

Contact with nitrates and other oxidizing materials, incl peroxides and other initiators of polymerization, strong alkalies, and atmospheric moisture may cause fires & explosions.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: EC50; Species: Pseudokirchneriella subcapitata (Green algae, age 3-7 days); Conditions: freshwater, static, 24°C, pH 6.3-9.3; Concentration: 15.53 mg/L for 96 hr (95% confidence interval: 0-46.78 mg/L); Effect: decreased population biomass
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Methyl acrylate, present at 100 mg/L, reached 37% of its theoretical BOD in 14 days using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). It has been suggested that methyl acrylate should degrade by biological sewage treatment processes with suitable acclimation(2).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for methyl acrylate(SRC), using a log Kow of 0.80(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl acrylate can be estimated to be 6(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl acrylate is expected to have very high mobility in soil. Methyl acrylate is highly soluble in water and, therefore, is not expected to significantly partition to sediments(3).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods
